Title: Integrator circuit consisting of switches, capacitors and an operational amplifier
Inventor: NOSSEK JOSEF DIPL ING DR
IPC: H03H19/00
Filed: 1981-07-16
Abstract: In this integrator circuit, the noise of the operational amplifier is taken into consideration by means of an equivalent noise source connected in series at its input, and the switches are operated by at least two different clock phases within one sampling period. It is the object of the invention considerably to reduce the so-called 1/f noise in such circuits. This object is achieved by the fact that the noise voltage (UR) of the operational amplifier is stored in an auxiliary capacitor (8) during a clock phase ( theta ) in which the operational amplifier is not needed for signal transmission, and, in a further clock phase ( theta ) in which signal charge is transferred to the integration capacitor (7) and output signal (Us) is output, this auxiliary capacitor (8) is connected with reverse polarity in series with the input of the operational amplifier (10) and to its noise source (UR). <IMAGE>

Title: Apparatus for dividing and isolating bottles arriving in a plurality of tracks onto a single-row track
Inventor: KARASS HANS-JOACHIM
IPC: B65G47/68
Filed: 1981-07-23
Abstract: In an apparatus for dividing and isolating bottles arriving on a plurality of tracks onto a single-row track, the back-up pressure during the transition from the wide-track conveyor to the associated isolation section is to be reduced. To this end, the wide-track conveyor is arranged perpendicularly to the transporting direction of the belts of the isolation section and, with its end face, makes full-face contact with the first track, running transversely thereto, of this isolation section, the first and subsequent track of the multi-track isolation section having a constantly increasing belt speed. With this linking of the isolation section to the wide-track conveyor, a substantial reduction of the back-up pressure still present in this region is achieved as a result of the take-off direction of the front bottles extending transversely thereto.

Title: High-voltage switching chamber having a discharge-free compression cylinder
Inventor: SLAMECKA ERNST PROF DR TECHN
IPC: H01H33/82
Filed: 1981-10-08
Abstract: In a high-voltage compressed-gas switching chamber in accordance with the autocompression method, and having stationary double nozzles, it is intended to prevent electrical partial discharges (which occur during both switching on and switching off and reduce the dielectric strength of the contact gap) between the wall of the opening in the base of the compression cylinder and the conductive material nozzle. The invention achieves this object by making electrical charges of different polarity comparable and by charge equalisation. According to the one solution method, an electrically conductive filling material, for example graphite or metal powder, is added to the base of the compression cylinder, which is produced from insulating material, in the region of the opening in order to make the electrical surface charges and the electrical field caused thereby comparable. Said addition is expediently carried out such that the shape of a body of revolution is produced by the distribution boundary. In order to make the electrical field homogeneous, the soffit of the opening in the base of the compression cylinder can also be metallised. According to the other solution method, the gap between the soffit of the opening in the base of the compression cylinder is electrically short-circuited. For this purpose, a metal-brush-like device is fitted either to the wall of the opening in the base of the compression cylinder, or in the end region of the conductive material nozzle, in order to "wipe off" the electrical charges.

Title: Electrical circuit for warning indication of a closed circuit
Inventor: DEPIL HERMANN
IPC: G01R31/02
Filed: 1982-11-11
Abstract: In my invention, an LED display is installed for each load point at a visible location. As long as the circuit is not interrupted, the LED display is illuminated. If, in contrast, the circuit is interrupted by a defective lamp, the LED display is extinguished. This makes it possible to check at any time whether a lamp is defective. My invention is interposed into new or existing electrical installations. Each lamp has an LED warning display. Two circuit examples for a load point of 5 watts and 21 watts are attached to the invention. In the case of 21-W lamps, resistors of 47 ohms are interposed and in the case of 5-W lamps, resistors of 36 ohms are interposed, see circuit diagram example. The invention can also be used if other load points are required. It is only necessary to use different resistors. The particular field of application are car lamps which are difficult to check but are very important for safety, for example brake lights, tail lights, flashing lights front and rear. Naturally, the invention can also be used for other checks. <IMAGE>
